Kiril

"The brown Rahaga fired a lasso Rhotuka and dragged the green spider into the small crater that Dume had made. Just as the Rhotuka's energies dissipated, though, Dume activated his Noble Kiril and closed the hole in the pavement around one of the Visorak's feet."

The KanohiKiril was the Mask of Regeneration. It gave its user the power to repair damage to inorganic objects within their range of vision. The only difference between the Great and Noble Kirils was that the amount the Noble Kiril could regrow was smaller. Neither versions of the Kiril could heal organic damage; only the Great Kiril could regenerate Protosteel.
